CAUTION

Connecting the DC Power Supply

Troubleshooting

If the Power Status LED and the switch Fault LED are flashing, one of

the following is probably occurring:

• The power supply is not connected to an active DC power supply

• The power supply is not properly installed

• A fault condition has been detected on the power supply.

To determine which condition exists, perform the following procedures:

1. Verify the power cable is connected to an active DC power source and

to the power supply. Make sure these connections are tight.

2. Try unplugging the power cable and plugging it back in to the power

supply.

3. If the Power Status LED continues to flash, verify the DC power

source works.

4. If the previous steps do not solve the problem, try removing and

reinstalling the power supply.

Disconnect DC power from the power supply BEFORE installing or

removing the supply. Not disconnecting the power first can damage the

power supply or switch. Read this manual for proper handling

procedures.

To avoid power supply or switch damage, do not attempt to power-up the

power supply outside the switch chassis. The power supply requires a

load and other enabling signals to operate properly.

If the power source and power cable are operating and this condition

persists, the switch power supply may be faulty.
